Recording
You can set the sound quality to use when recording.
Improving the sound quality increases the song size and decreases the recording time.
When making a final recording of a performance, it is best to use WAV 16 bit or 24 bit to
give priority to sound quality.
When making an audio CD, set the sampling frequency to 44.1 kHz and the recording mode to WAV 16
bit.
Test recordings and records of meetings do not usually require sound quality as good as
that. For longer recordings that give priority to song size, use MP3 128 kbps at 44.1 kHz.
Decide whether the sound quality or the recording time is to be given precedence, and
make the settings accordingly.
The larger value provides better sound quality.
When making a digital recording, the sound level is measured periodically, and that level is
made into a digital signal. The sampling frequency is a value that defines the time interval
and is expressed in kHz. A high sampling frequency is needed to faithfully reproduce high
sounds.
• Higher sampling frequencies result in larger song sizes and shorter recording times.
• When using the recording as an audio track for a video, we recommend setting the frequency to 48 kHz.
• The sampling frequency of a recorded song cannot be changed on the R-09.
